0027793: Visualization - object drifts at zoom within Graphic3d_TMF_TriedronPers applied

Browse Source 
Graphic3d_TransformPers now takes Graphic3d_Camera definition as argument
for methods applying transformation.

Graphic3d_TransformPers::Apply() now computes Graphic3d_TMF_TriedronPers
transformation in the following way:
- The object is moved onto Z focus distance.
- The object is expected to be defined in pixels.
- The Z coordinate on anchor point is used as offset from the view corner in pixels.
- It is now possible to define not only corners of the view, but also middle of the side.
- Graphic3d_TMF_TriedronPers now works with perspective projection.

OpenGl_LayerList::ChangeLayer() - fixed removing of the element in old ZLayer.

OpenGl_Layer::BoundingBox() now takes into account bounding box
of Graphic3d_TMF_TriedronPers presentations for Z-fit operation.
